What can you extrude in AutoCAD?

Creates a 3D solid from an object that encloses an area, or a 3D surface from an object with open ends. Objects can be extruded orthogonally from the plane of the source object, in a specified direction, or along a selected path. You can also specify a taper angle.

Can arc be extruded in AutoCAD?

Select the lines and arcs that would make up one plane of your 3D solid then type region on the command line. The lines and arcs are then replaced by a “region” object which can then be extruded to form a 3D solid.

Which object can not be extruded Mcq?

What does UCS do in AutoCAD?

The user coordinate system (UCS) establishes the location and orientation of a movable Cartesian coordinate system. The UCS is an essential tool for many precision operations. By default, the UCS icon appears in the lower-left corner of the drawing area for the current model viewport.

Why extrude command is not working in AutoCAD?

That’s obvious because EXTRUDE works only on complete closed objects, not lines. If your drawing is closed for example like a rectangle, but it’s made with the command LINE, then you select all the lines of your object and type the command JOIN, to make all the lines one object.

What is Presspull in AutoCAD?
